Step-by-step guides

What the manual does not say

2 jobs with nothing stated
  • Descale
  • Drip tray empty & clean
Notes from the research
  • Slayer's schedule is written for heavy commercial use; only backflushing and screen cleaning carry explicit home cadences.
  • No descaling guidance (scale is handled by mandatory water treatment) and no drip-tray step.
  • No water tank, so water_tank_clean is omitted; water_filter_replace is kept because the maker mandates a plumbed filter.
